vide an improved form of centrifugal pump:

having a rotary lpiston of improved construel tion and arranged relatively to the inlet and discharge optmings so, es to secure great eiliciency with simple and inexpensive construction.

A further object of the invention is to iniprove the construction oi the rotar` piston or runner so as to reduce skin sur'l'yece and. thereby reduce the fric tion and avoid impact or concussion.

A further object of my invention is to provide a cut-oil device for the discharge opening so that this discharge opening can be ac con'nnodated to any given quantity.

A further obj ect of the invention is to provide an improved freine construction by which the various parts are kept in perfect alinemcnt.

A further object is tojprovide improved means for lubricating the bearings and also to improve the construction of the hearings.

A further object is to )rovide a discharge nozzle which can be readily madeto it'any size discharge ipe.

A further o ]ect is to provide a knife shaped' `discharge. cutter by which correct ow of water isvobtained for highest elliciency.

M y invention consists in the constructions and combinations ot parts hereinafter described and set forth inthe claims.

Like par ecters of reference in the accompanying' In said drawings, e represents an arch shaped freine mounted upon a suitablesupportingr base, al. This-1u "i france at one end the pumping cylinder and 1 pis-I ton and at the other end thc beer-ings, c, for the driving shaft for the piston.

The cylinder is formed of two parts in the usual wey, the main easing, b, and thecylinder head, b1, and is bolted or otherwise secured, to this yoke-sha edil-aine. The ey]- inder is provided with t ie'usual supply opening, b2, towhich may be holted any suitable supply pipe, (not shown) and also with a, dis charge openi b3, of novel construction which will he described hereinafter.

Located within the cylinder is a i'o'tary piston, d, also of novel construction.l This rotary piston., d, hascurved blades, three of which, dl d1 di, ere shown in the present instance, radiating from the hub, d, of the piston to the outer periphery of the cylinder, where they are attached to a'medial, peripheral ring, d, that the ringr is centrailly located with reference to the width' of the blades, d, so that said blades will pro ject laterally on, either side of said ring, heing also inclined towards the periphery of said ring as indicated at d. Located on either side of this ring,d', intermediate the respective blade portions, d, are a series of oquall4 f repre-senti, hy similar chen loo spaced inclined varies, d5, the inclination and creasing at the same time the amount of skin.

surface touched. bv the water and avoiding excessive end thrust toward the suction side, as is usual in other pistons.

By the construction of the piston, as described, with the curved and radial blades which connect the medial pcrijiheral ring with. the hub, having the extcinlcd screwshaped ends when ex tend into and terminate in the suction 'pening, causes an inflow of the liquid acted upon without impact. l also preferably form tho screw blades where they enter the inlet opening at an angle of substantially for tive degrees to a plane at right-angles to th oi" rotation. l. also jvrefcrahly forni the suction opening of such a dianutcr that thc inlet velocity of thc liquid through said suction opening equals the peripheral vrdecity of the revolving piston in a zene with. 'the diameter of said suction lenf-shaped blades, it will j ill be curved from the inclined por ons to the point where they join the medial ring, at which point they will be substr ially at ri ht-angles to said ring in 'cross tion, as .ilxown in Fig, 3. These d screwshapcd blades will also be gradually tapered on the extended. portion so as to permit thorn to terminate within the inlet opening as described, thus obviating. the use of dillusion vanes and causing water to ie acted upon directly by the blades at the proper angle and inlet velocity to prevent im act and therefore with minimum amount of iiriction, v

Thermain frame a, as before stated, is n nnu'ited' upon a suitable base and carries at one ond the cylinder and its piston and at the other end isproridcd with a bearing, c,

ior the lriving shaft j", which drives thc ton. This main frame is formed archshaped and has 'a strengthening rib c2.. The cylinder hond is secured to this irai'nc at one ond and the frame cylinder head and base form substantially one part. .At thc cylindcr ond oi' the frame it is provided with the usual stulling box, a,- through which the` driving-shaft passes. By this construction of sfu )porting frmnc and nnulncr of mountlic operating mrts thereon, thc parts will he kopt in pcrflcct. nlincnient.

'lhe bearing, c, lfor thc driving shali,f, is formed. with a hollow chamber which has sccured to the outer end thereof' a removable .Cap c1. In this chamber the shaft runs in two brass bushings, cs c, as shown in Fig. 1, these respective bushings being provided with openings c7 and cx3 on the top and slots c and cl2 extending from said openings in a )arallel direction with ,the axis of rotation.

lhe bushings are located in the walls ot' the chamber and cap respectively at one end and also between the webs c2 c3 and cs c9 respectively at the other' ends. The bushings receive oil either from a rib runninfY along the top of the hollow chamber parallel' to the axis of rotation or by projections, c, extending inside the hollow chamber above the shaft, these projections being located on the ca cx and being preferably two in number. Al of these -Ineanscatch the oil which is thrown around from the collar, c, and lead it over to the rec ective openings, c7 c, of the bushings. T ic collar, c, is adjacent the bushing, c, and secured to thc shaft by a pin, 0"", so as to revolve there-with, and forming a bearing point onthe face ad jacent the bushing c, which bushing is enlarged as shown at c to receive this bearing point of the thrust collar and take up the thrust thereof. The thrust collar isvprovidcd with two or more longitudinal passages cu c and also at one end with openings, c1 c, which connect the respective passageways, 617.0", with the interior `of the chamber, Loosely hung on the shaft adjacent to the thrust collar is a ring or chain, 022, (shown in the drawings as a ring) 4 the bearin r', the lower 'part Yof thev-hollo'v 'chamber will be filled with oil, which oil will be carried up by the ring or chain around to the shaft and adjacent to the passagesways,

cc, in thc thrust collar. T lis thrust collar, acting as a centrifugal pump will draw the oil inwardly throu fh the passage-n'ays, c17 c, in the thrust col ar and will discharge the` oil through the openings, cla c, against the 'inclined projections, c, or thc ribs .inentioned, where it will be deflected and will find its way into the bearings properO by rcason of the longitudinal )lissage-ways and openings heretolore deserl ed in connection with the bushings, 1:5 c.

In order to regulate the l uantity of liquid discharged by the pump, I ave rovided at the point of discharfre a knife-e( ged cutter,"

adapted to shear olf from the revolving body" of liquid inside the casing a band of liquid of a width corres'ionding to the sircd to be discharged, thus pro( ucing a correct and uniformA discharge of the liquid through the discharge opening and securing thv l-est eflieiency of'the pump. In order lto accomplish this l. have made the discharge passage or housing, b3, removable and lo` cated at the point of' discharge 'from the casing a knife-edged cutter, y, adapted tovcxtend partly Within thc casing or cylinder.

In: the operati'onfof uantity dc- 25 the refpiircments.

40V charged by the piston.

The casing or cylinder is formed circular so that it can be easier machined, and is rovided with an opening, g1, at the point o its periphery whereit is desired to locate the is c arge. About this openingA there is formed onl the casing or cylinder aflange, g, to which flange the discharge housing, b3, is secured, said dischar e housing, b, being likewise provided wit a fian e, g, and the respective flanges provided wit bolt holes to receive bolts to secure them together; the bolt holes of the anges, g2, being shown in Fig. 18 and indicated by the reference letter if. The knife-edge cutter, g, is secured `to the flange, g2, by screws, g", said flange being provided withopenings, g, shown in Fig. 18

to receive these screws. The dischar e housing, e, is provided with an upwardy extending flange; g8, ada ted to be bolted to 20 the cylinder head. By t is construction the shear or cutter can be ,easil and uickly removed so as to be replaced by anot er cutter diii'erent in length so that the quantity of water discharged can be re lated to meet When this shearing knife is ein overl extending partly into the casing or cy inder across the discharge opening, the rotary piston will, of course, not extend to the outer wall of the cylinder as illustrated in Fig, l but will be reduced in diameter so as to` leave an o cn space between its outer periphery and t ie wall of the casing or c linder so as to clear the cutter as shown in ig. 15. The discharge opening b3 formed by the dis- 85 charge cutter will bev s uare in cross-section or su1 stantially so an the endvof the discharge outlet, b, will he yformed square in cross-section, as shown in Fig. 5, so as to conform with .the shape of This discharge opening, b, is formed with a finished face and secured thereto is a discharge nozzle as shown in Fig. 4 which is also formed square.

in cross-section at the point of connection as 46 indicated at el and is tapered or reduced towards its discharge or outer end asindicated at e and formed screw-threaded as shown at e3 to receive the screw-threaded end of a suitable discharge pipe. By this construction 50 of the nozzle it can be adapted to fit any size dischar e pipe by simply cutting the nozzle ofi' at different points to obtain any sized o enin desired and then screw-threading t e en( to conform lto the sizeof the dis- U charge pipe to which it is to be connected.
